DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0027] The present invention provides a drainage control device and a cleaning robot. The
present invention will be further described in detail below with reference to the
accompanying drawings and embodiments. It is understood that the specific embodiments
described herein are merely illustrative of the invention and are not intended to
limit the invention.
[0028] Referring to FIG. 1 to FIG. 6 together, the drainage control device of the preferred
embodiment of the present invention includes: a water tank body 9 and a middle cover
2 sealingly disposed on an upper portion of the water tank body 9. The middle cover
2 is provided with a water inlet 21, an air inlet 22, and a steering engine assembly
3 matched with the air inlet 22, the steering engine assembly 3 is configured to adjust
the opening size to control the air intake amount, a sealing cover 4 is mounted on
the water inlet 21, and a least one water outlet 91 is arranged in a lower portion
